Shipping these large frames is not easy. Bobby ships them with flat rate shipping so you can order as many frames as you need with a flat $16 rate.
Bobby is sending some frames to me. Will put them up on my website on Wednesday. Should save some money on shipping costs.

We are working on reducing the cost. Currently the frames are made in USA.
Also considering plastics to reduce cost. The current aluminum frame helps dissipate the heat from heatsink better.

Time for a deep cut, because if you don't love Jonathan Richman you should:


@robincnn what kind of plastics might be suitable for something like this? I guess you'd need tough and UV resistant, but plastic sounds fun.

So much for pre set Aromid fabric [aka kevlar] :)

but seriously, why not use plastics and in all serious ness though Jorge, isn't one of the big things about, well, just cobs, so outside of that, this argument this is null, but.. not having UV?

I come from a past in semi professional rallye racing, on the build side. The one constant in just about any car is Lexan. I mention specifically Lexan because there is a process to coat for UV damage because the Lexan becomes "smokey" as they say from repeated exposure to the sun. So UV exposure is available if we built the case out of bulletproof glass, which sounds funny to say, but that is after all what Lexan is. Of course we were using moderate 1/4" thicknesses. I believe the president's limo is 4+ inches?

There was also another ABS derivative we used for building driveline and brake line "rock coverage" on the car's underbelly [pan], can't quite recall the name though...

What about a carbon fiber wrapped plastic case?
[ok, this one is probably a product of too much :joint: ] :peace:

I love Lexan! Super easy to work, strong and doesn't shatter if you sneeze on it like acrylic. Only reason I mentioned UV is some people like to add it with extra bulbs. That and far red seem to be the two main additions to cobs.

Isn't polycarbonate kind of expensive in the thickness we would need to support a shape like these frames? Maybe it would make up for it with the cost of machining. It would also look super cool.

what's the benefit of silicone lens and will these fit onto the predilled heatsinks from cutter from the MAU kit?

Kinda the best of both worlds between glass and acrylic. Clearer than acrylic and more scrach resistance than glass. Plus decent weight savings.

They will not fit the cutter heatsinks as far as I know, need a special bolt pattern.

Bravo guys, MOD 420 looks amazing and fills a much needed niche that will help even more people discover that DIY led growing is where its at.

Some notes on the design:
-the vast majority of your production costs comes from Waterjet run time aka cut time.
-everytime the waterjet machine has to pierce a hole in the material, it has to move to that position, pause a second, begin pierce, then proceed with the cut. the whole time, the clock is running and you are paying for that time whether the abrasive is flowing or not.
-once the waterjet is cutting a path, it is actually very fast and cost efficient.
-if you could make any of your holes contiguous , or combine multiple holes into slots this will save you big time.
-any holes that are near the edge of the material (inside edge or outer perimeter) can be turned into slots that are contiguous with the perimeter.
-a bit more optimization of the design file can save you at least 25% on your costs, im completely confident in that.

Very smart. And the holes you cut out in the cenyer for cobs, could be run into the center with a continuous cut.

Thank you sir! I'll definitely continue play around with that and re quote.
